Warren Buffet says that he "borders on lethargy", his style is about making few decisions except the really important ones. This helps him stay relaxed, focused and thoughtful.
That is an important lesson, if you really think about it do the decisions made by you, every second of the day, really need your input? How many smaller decisions are sapping your energy? Give people the power to make day to day decisions and free yourself up to be thinking about the direction your team should be taking and how to get the best out of your talent.
Great words of advice from Mr Buffet!
